I am currently with Verizon. Phone. Wireless router. Computer now hooked up yet. Only samsung galaxy phone. (MY ONLY PHONE)and use it for FB.. email. Google. Don’t watch movies. Use youtube except for some fb posts. This month ive even tried to disable mobile data when out. For some reason my Verizon Bill has taken a giant step from 200.00. To $700.00 this month.. Frim 8 gb to 44 gb. They informed me that the router Is using the most data. Doesnt make sense. I want an unlimited data router. Have tried my direct tv. They don’t bundle in my area. Live across from Northwood HS. I had century link which didn’t work a lot. HELP !!! WHAT CAN I DO????
.THANKS AHEAD FOR ANY GEEK ADVICE. I AM PROUDLY A LUDITE.
